Switch to the privileged EXEC mode.
Switch to the configuration mode.
Disable Strict Priority for the priority classes 0 to 5
and thus enable Weighted Fair Queuing. The prio
-
rity classes 6 and 7 remain in Strict Priority mode.
Assigns the weighting to the Weighted Fair Queu-
ing priority classes. In the case of Strict Priority,
because the Switch first transmits all the data
packets with a high priority, you can enter the
weighting 0 for the Strict Priority priority classes
and distribute 100% among the remaining priority
classes. The Switch distributes the remaining
bandwidth in accordance with the percentage
weighting.
Assigns a maximum bandwidth to all priority
classes (Shaping).
Because the two Strict Priority priority classes are
limited to a maximum of 30%, the remaining
queues have at least 40% of the bandwidth at their
disposal. The Switch immediately sends Strict Pri
-
ority data up to a maximum bandwidth of 30%.
Switch to the privileged EXEC mode.
